Intermolecular CO-retained carbothiolation of alkynes using thioesters took place to afford beta-SR substituted enone derivatives; the choice of catalyst (Pd(dba)(2)-dppe) and the introduction of a CF(3) group into the thioesters are the key to achieving the transformation.
使用硫代酯进行炔烃的分子间CO保留的碳硫羰基化反应,得到β-SR取代的烯酮衍生物;选择催化剂(Pd(dba)(2)-dppe)以及将CF(3)基团引入硫酯中是实现转化的关键。
